Comments & Wishes ⇒ Accessibility

[Astor]

Hello. Below is a tex file that I copied from the Latex project. When I run my accessibility checker (Ally) it shows the mathematics as images and my screen reader won't the math. It's my understanding that \DocumentMetadata should convert the x, x-squared and the matrix to MathML. I'm not sure if I missed something or not, but any advice on how to make the math accessible would be appreciates. Thank you!
